PNEUMATIC DISPATCH DEVICE.

SPECIFICATION forming part of Letters Patent No. 542,919, dated July 16, 1 895.

' Application filed April 12, 1893. Serial No. 470,046. (No model.)

.To all whom it may concern.-

Be it known that I, SAMUEL W. BARR, of Mansfield, in the county of Richland' and State of Ohio, have invented certain new and useful Improvements in Pneumatic Dispatch Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvementin pneumatic dispatch devices, and more particularly to an improved automatic switch or ejector used in connection with such devices, the object of the invention being to produce simple and efficient devices whereby the car or box of a dispatch device can be easily, quickly, and automatically ejected at a certain predetermined station.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view illustrating my invention, a portion of the tube being broken away to show the position of the parts in the act of ejecting a box or car. Fig. 2 is a face view of the tube. Fig. 3 is a cross-sectional view of the tube and easing. Fig. 4 is a view of an ejector or switch adapted to eject a box or car having a ring v Figs. 5 and 6 are detail views.

A represents a dispatch-tube showing a portion cut away to illustrate the positions of the parts in the act of ejecting a box or car. At each station on the line of the tube onehalf of the tube is cut away, as at a, at an angle of about eighty degrees from horizontal, so that the lower portion extends beyond'the center to produce a track for cash boxes or cars which pass on to other stations. The opening in the tube is normally closed by means of a gate B hinged at one end thereof to the tube and retained normally in place by meansof a light spring B. From the side of the tube opposite the opening a a lug (or lugs) 9 projects, to which a car-ejecting lever O is pivotally connected. The arm b of the car-ejecting lever 0 projects forwardly and outwardly through a slot 1) in the tube, and

the arm b of the lever O is provided with a heel b which projects towardsaid slot in the tube, in which position it is normally retained by means of a spring 0. At points between its ends the locking-lever D is provided with laterally-projecting pins, which, when the device is operated in the manner presently explained, will pass through notches d in the tube, said notches d communicating with the slot b.

The switches or ejecting devices at the severalstations along the line of the tube are each adapted to eject a certain car or box E, and each car orbox is adapted to be operated by a certain switch or'ejector.

The adjustment of the various ejectors to operate upon certain boxes or cars is regulated or determined by the relative position of the locking-lever D on the car-ejecting lever O, and the boxes or cars E are adapted for certain switches or ejectors by means'of rings E thereon, said rings being arranged on the several boxes or cars at difierent distances from one end thereof;-

Should a ring be arranged in the center of a box or car, it matters not which end of the box or car is inserted into the tube first by operator; but if the box to be passed through the tube should have the ring nearer one end than the other, it is important that the operator should so place the box or car in the tube that the ring shall be nearer the end of the box or car last'to enter the tube.

It a box or car be provided with two rings equally distant from the center of the box or car it would matter not which end be placed in the tube first.

Instead of providing. the boxes or cars with rings at points between their ends the boxes may be made of different lengths.

In Fig. 1, I have illustrated a box or car having a ring E at one end thereof immediately in rear of the felt bands 6 on the heads of said box or car. When this box or car reaches the ejector or switch shown in Fig. 1, the front end of the box or car'will strikethe arm I) of the car-ejecting lever O, and simultaneously the ring E at the rear end of the car or box will strike the trip D and turn the same sufliciently to cause the pins d to pass the notches d in the tube. The momentum of the box or car will cause the car-ejecting lever O to turn slightly on its fulcrum and cause the pins d to ride on the tube A out of line with the notches 01, thus locking said lever. The momentum of the car or box will therefore cause it to force the gate B open, the continued movement of said car or box through the tube being prevented by the arm I) of the car-ejecting lever O. The box or car E will thus be ejected from the tube.

Boxes or cars having rings E between their ends will operate in the same manner as above described. such intermediate rings serving to operate the locking-lever D.

The switch or ejector shown in Fig. 1 is adapted to eject a car or box having the ring E at the end, and is therefore located in close proximity to the heel b When the switch or ejector is adapted to eject a box or car having an intermediate ring E, the trip will be arranged nearer to the fulcrum of the lever 0, according to the location of the ring on the car or box, as shown in Fig. 4. The purpose of the heel b is to prevent the passage of one box or car while another is being ejected.

The lever C will be maintained normally in its operative position by means of as'pringf, secured at one end to said lever and at the other end adapted to bear on a pin f projecting from the lug g.

It will be seen that when a car or box which is too short for a certain switch or ejector passes such ejector it cannot be ejected because the forward arm of the lever and the trip will not be engaged simultaneously by the car or box, and consequently the lever will not be locked, but the lever and trip will swing out of the way and permit the car to pass. So, also, if the ring on the car is notin the proper position for a certain station which it reaches the lever will not be locked and the car or box will in a similar manner, as above described, be permitted to pass on until the proper station is reached.

In order to prevent leakage at the stations the openings in the tube and the switches or ejectors will preferably be inclosed by a casing F, having valves F F, said valves being so constructed and arranged that but one will open at a timefor the passage of a box or car.

The apparatus is very simple in construction, automatic in operation, not easy to get out of order, and is effectual in the performance of its functions.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a pneumatic dispatch tube having a discharge opening therein, of a pivoted car ejecting lever and a looking lever carried by said lever, said devices being constructed and arranged to eject a certain predetermined car or box, substantially as set forth.
